About the LGPL packages. Dompdf and its two helper packages are licensed under the LGPL. They are used unmodified, and their full source is included in the vendor folder. That meets the LGPL. If you change them, the LGPL asks you to share those changes.

Fonts

The two typefaces, Fraunces and Inter, are used under the SIL Open Font License 1.1. Both are included in the package. Nothing is loaded from an outside server at any point, so your site keeps working even where Google Fonts is blocked.
